Selling a campervan to another foreigner in Costa Rica

Selling a campervan to another foreigner in Costa Rica

Hi everyone, we are currently selling our van in Costa Rica. Ideally we would like to sell to another traveler but were wondering what people's experience with this was? How easy was it passing it along? What happens with paperwork etc? Does anyone have any experience with handing over power of attorney here in CR to potentially avoid the large import taxes?
